The Kids Are All Right is that kind of movie that, apparently, could be a typical comedy/drama but when you watch it you realize it's not.
Two lesbians with a daughter and a son, act as every family would do until the biological father of both kids appears. From that point on, the movie is a mixture of comedy with drama that keeps the person on the edge of his seat, wanting to know how everything it is going to end.
The film, then, has something "special" that I cannot explain properly but that could be described as a mixture of relationship feelings, family feelings mixed with the feelings of two teenagers that are in the middle of everything.
I liked a lot this movie because I did not had to be looking at my watch to see how much time there was left, I just enjoyed the magic of this film. A part from that I have to say that the script was, from my point of view, very well written, and Mark Ruffalo and Anette Bening make sensational performances, especially Anette that really does a very good work.
